What's the Classification of Welded Pipes?

Jun 24, 2017

    Classification of welded pipes:



Production Standards according to GB9711.1/GB9711.2/API 5L PSL1/PSL2/EN/BS/JIS/DIN etc

Spiral welded pipe(SSAW Pipe) out diameter from 219.1mm to 3000mm even more.

Spiral welded pipe(SSAW Pipe) Wall Thickness from 5mm to 25.4mm.

Spiral welded pipe(SSAW Pipe) Length from 1m to 16m.

The SSAW Pipe price is cheapest in Welded Pipes.

Spiral welded pipe(SSAW Pipe) is widely used in natural gas, oil, chemical, power, heat, water supply and drainage, steam heating, hydro power station pressure pipe, thermal power, water and other long-distance pipeline and piling, dredging, bridges, steel and other engineering fields


2:LSAW(longitudinally Submerged Arc Welding)

Production Standards according to API 5L PSL1/PSL2/GB9711.1/GB9711.2/ASTM A53/ASTM A252/ASTM A672/EN/DIN/JIS etc

LSAW Pipe out diameter from 325mm to 1820mm

LSAW Pipe Wall Thickness from 6mm to 80mm even more

LSAW Pipe length from 1m to 13m

LSAW Pipe price is High in Welded Pipes

Longitudinal submerged arc welded pipe(LSAW Pipe) in the heavy steel structure engineering and fluid pipeline engineering, foundation piling project has been widely used

3:ERW Pipe(Electric Resistance Weld Pipe) 

Production Standards according to API 5L PSL1/PSL2/GB3087/ASTM A53/ASTM A252/ASTM A672/EN/DIN/JIS etc

ERW Pipe out diameter from 21.3mm to 660mm

ERW Pipe Wall Thickness from 1mm to 18mm

ERW Pipe length from 1m to 50m even more.

ERW Pipe price is High in Welded Pipes

ERW Pipe(Electric Resistance Weld Pipe) Useful:For liquid delivery with: water supply, drainage. For gas transportation with: gas, steam, liquefied petroleum gas. For the structure with: for the piling pipe, for the bridge; terminal, road, building structure and so on
